If the result is outside the usual range
A high amount of CMV DNA can point to active CMV disease in that organ, such as the gut or lungs, especially in people with weak immunity. Low amounts are harder to interpret.
Who usually has this test
People with weakened immunity, such as after a transplant or with HIV, who have symptoms in a particular organ.

Questions about this test
Why test tissue rather than blood?
CMV can cause disease in one organ even when blood levels are low. Testing the affected tissue gives more direct evidence.
What does quantitative mean?
It means the lab reports how much virus DNA is present, not just yes or no. This helps tell active disease from low-level presence.
Can healthy people have CMV in tissue?
Many people carry CMV silently after a past infection. Small amounts can be found without disease, so results are read with symptoms and biopsy findings.
